'TSIPEWRITING MACHINE.

Application filed May 6, 1922. Serial No; 558,951.

T 0 all whom it may concern.' A

Be it known that I, Josnrn B. HOLDEN, citizen of the United States, and resident of Syracuse, in the county of Onondaga and State of New York', have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

My invention relates to typewriting ma` chines and more particularly to carriage escapement mechanism, and to the manner of mounting and connecting parts thereof and their actuating means and corre-lated devices.

The main object of my invention, generally stated, is to provide comparatively simple and eiicient means of the character specified.

A further obj ect of my invention is to pro vide a construction such as that referred to, which may be made light in weight without sacrificing efficiency and may be includ-- ed in a small compact portable machine, af- 1fording ready access to the parts nevertheess.

To the above and other' ends which will hereinafter appeal', my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following-description and particularly pointed out in the appended claims.

In Ithe accompanylng drawings wherein like reference characters indicate correspending pa-rts in the various views,

Figure 1 is a fore-and-aftvertical sectional view. with parts omitted, of a machine embodying my invention.

Figure 2 is a fragmentary top plan view of the same, with some of the parts disclosed in Fig. 1 omitted.

Fign1'e3 is a detailfragmentary front view of the combined fulcrum vand comb plate and some of they associated parts.

l have shown my invention in the present instance embodied in a Remington portable machine. where it aidsmaterially in the production of a light, colnpact and highly efficient machine. It should be understood, however, that the invention may be embodied in other styles of machines.

J. B. Holden, Sr. No. 531,649, filed Jan. 25,

The frame ofthe machine comprises an outer sheet metal frame 1 surrounding and fixed to an inner frame which includes sheet metal side plates 2 united by a hollow cross bar 3 and a casting 4. AThe various working parts ofthe machine are carried bythis inner fixed frame. As shown in the above mentioned Smith patent printing key levers 5 are fulcrumed on a fixed rod 6 carried by ak bracket 7 secured to the casting 4, and each lever is provided with al finger key 8. The various key` levers passthrough guide slots 9 in a sheet metal combined guide comb and fulcrum plate 10, best shown in Fig. 3. This guide comb .extends across the machine near the front thereof, and is secured to ears 11 on the side plates 2 by kscrews 12.

The upper portion of the plate 10 is slotted at 13 and 13a (Fig. 3) to receive and guide the forward sub-levers of thetype actions and also the space key levers, each of which fulcrums on the bottom wall of its respective slot,'as will hereinafter appear.

A `keeper plate 14 prevents the parts from beiiig dislodged from their -fulcrums, as disclosed in my above mentioned application.

Each key lever has the lower end of af link 15 pivoted thereto at 16, whereas the upper end of each link is pivoted at 17 to a sub-lever 18. The forward4 end of each of these sub-levers is fulcrumed on the plate 10 as explained above. Eachsub-lever 18 is also pivoted at 19 to a li'nli' 20, pivoted at its upper end at 21 to a second sub-lever 22.

These latter are'pivoted at 23 on a segmental casting 24 formed integral with the casting 4. The inner ends of the sub-levers 22 are formed with segmentally arranged rack teeth 25 that mesh with corresponding rack teeth 26 on the heels of the type bars. The type bars 27 are 'pivoted at 28 to a. segmenty whichv constitutes part of the caste the inner fixed frame.

carriage support 36, and the case shift yframe ing 4.. Each type bar carries a lower case type a and an upper case type b.-

depression of the printing key 8 is effective to move the corresponding type bar downwardly and rearwardly to strike against the top face of a platen 29 'with either of the types a or b, depending onjthe case shift position of the platen.

The platen is supported by a carriage for traveling movement across the machine and for case shifting movement fore-and-aft of the machine, as disclosed in my above mentioned Patent No.`1,386,256, and as will now be set forth.v

The sheet metal bed 30 of the carriage, which supports the platen 29, has its edge portions bent to -form raceways 31 and 32 in which crossed bearing rollers 33 are received. "These rollers are also received in ways 34 and 35 formed in plates secured to an aluminum casting 36. This casting formsa support for the carriage and over which the latter travels, and with which it moves fore-and-aft of the machine in its case shifting movements. The support 36 constitutes a portion of a case shift frame and carries depending slotted lugs 37 in which are pivoted, at-38, the upper ends o'f arallel arms 39 fixed to a rock shaft 40. aid shaft is mounted at its reduced ends in bearing openings in the side plates 2 of 1n this manner the of which it forms part, are supported at the rear of the machine forA case shift movement. The support 36 is detachably fixed by screws 41 to horizontally disposed sheet metal anges 42, each formed as a part of a side member, plate or bar 43 that extends fore-and-aft of the machine., The 'forward end of each member 43 is pivot-ed at 44 to a depending link 45, pivoted at its upper end on a pivot pin 46 which extends in from the companion side plates 2. 'A cotter pin 47, extending through an opening in each pin 46, prevents an accidental detachment of the associated link 45 from its pin.

Suitable stops 48, adjustable on each side plate 2, co-operate with a stop 4'9, secured at 50 to the companion member 43 of the shift frame, to arrest its case shift movements.

Any suitable key controlling means may be employed to shift the case shift frame.

In the present instance al pin 51 projects from the left-hand Abar 43 and coacts with the depending arm of an angular lever 52.

This lever is pivoted at 53 to the left-hand` side plate 2 of the linner fixed frame. A depending link 54 is connected at its upper end to a forwardly projecting arm of the lever 52; the lower end of the link being 4pivoted, as indicated at 55, to a shift key ever 56carrying a shift key 57. The lever 56, like the printing key levers, is fulcrumed at 6 on a fixed part of the machine. A demessie pression of the` key 57 is effective to move the case shift frame with the parts carried thereby rearwardly from the position shown in Fig l, and present the platen in position to receive the impact of the upper case types b on the type bars.

Aside from the type actions and space key, most of the other working parts are mounted .to shift with the carriage, and thus ranged beneath the carriage support 36, the

carriage and platen, and extending foreand-aft of 'the machine. The dog rocker comprises two tixedly connected sheet metal plates 63 and63a. One of these plates 63 is formed with depending ears 64, apertured to receive they reduced pivot bearing ends 65 of two screws 66. These screws are threaded into tapped openings in depending ears 67 of a sheet metal bracket 68, secured by" screws 69 to the bottom of the carriage support 36. Lock nut 7 0 holds the pivot screws 66 a ainst accidental displacement. -A rearwar ly projecting linger 71 on the bracket 68 coacts with the dog rocker to limit the upward movement of the rear end thereof. A pin 72 projects up from the plate 63 of the dog rocker and is surrounded by a coiled expansion spring 73 that bears at its lower end against the dog rocker. The upper end of the spring bears against the carriage support 36; the spring passing through a hole 74 (Fig. 2) in the bracket plate 68 to reach the support, andthe side lwalls of the hole 74 together with the pin 72 retain the springagainst lateral displacement.

The plate 63a of the dog rocker is extended to provide a forwardly projecting integral arm 75, by which the dog rocker is actuated from the printing keys and from .the space key through separate trains of where connection is madewith the universal bar 77 vby spot-welding or otherwise. The arm 82 also projects rearwardly from its bracket 80 and carries a laterallyvprojecting Vpin or contact 83 at the rear end portion thereof. This contact is arranged beneath a laterally projecting integral lug or contact 84 on the arm 75 of the dog rocker, there being a lost motion between the contacts before the contact 83 coacts with the contact 84.

It will he understood that the depression ot' a printing key 8'is effect-ive to depress the universal har, thus rocking its frame and swinging the contact 83 up. When the contact 83 reaches the contact 84, the dog rocker will be rocked, moving downwardly at its rear end and moving thedog 61 out of the rack and the dog 62 into engagement therewith. On the return of the dog rocker f the carriage will advance one step under the power applied thereto by a spring drum 85. 'this spring drum is carried by the carriage Support 36, and is connectedto the carriage by a cord 86 which runs over a pulley 87 and is connected at one end to the drum and at the. other end 88 to the carriage.

As hereinhefore indicated, the escapement is controlled from the space key 89 by a separate train of connections which comprises two sheet metaL levers 90 tixedly connected at their forward ends to the space key. and each formed as shown in Fig. 1 with an inverted substantially V-shaped portion 91 received ina slot 13 in the combined tulcrul'n and comb plate 10. Each of the slots 13" is substantially twice the width ota slot 1?. so that a lever 90 and the adjacent sub-leveri18 may be received in the saine slot. 13, These levers 90 straddle the plate 1t) and fulcrnm on the bottom walls otl the slots 13" and extend rearwardly and downwardly from the plate 10. The rear ends ot' these levers are united by a cross bar 92 fixed thereto by screws 93. The Space key 89. levers 90 and cross bar 92, as viewed from above, constitute a rectangular frame t'nlcrunied intermediate its ends on the plate 1u. and returned to normal position by two Springs 92; one connected to cachlever 90. Fixed to the cross bar 92 intermediate its ends. and projecting rearwardly and upwardly therefrom, is a sheet metal arm 94. This arm, in the present instance, has a hole therethrough shaped to conform to the angular cross-section of the bar 92, which bar` extends through said hole. The arm 94 also has a laterally projecting integral foot piece 95 extending`at right-angles to the plane of 'the arm and fixed to the' cross bar 92 in any suitable manner, as by spot-welding. The rear end of thearm 94 has an upwardly extending open-ended slot 96 therein that 'is inclined slightly to the rear from the lower to the upper end thereof.` An upright link 97 is pivoted at its lower end by a cotter pin 98 to the arm 75 of the dog rocker, whereas the upper end of the link carries a laterally projectingpin 99 that projects into the slot 96 in the arm 94. l

This construction is such that in the shifting movement of the dog rocker with the Vcarriage support 36, the lower end of the link 97 will turn around the axis of the pin 99, which pin'at this time turns in its seat at the lower end of the slot 96 without atecting the operative connection between the space key and dog rocker. normal, or case shifted position of the dog rocker, an actuation of a printing key will cause thefdog 'rockerfto oscillate it in the mannerdescr-ibed'above. At this time the pin 99 will move up freely in the slot 96, while lthe space key and the remainder of its train of connectionsto the dog lrocker stand at rest. On the other hand, when the dog rocker is actuated by the space key the contactl 84 on the dog rocker will move upwardly away from the contact 83 and the train of actuating connections from the universal bar will remain at rest. Therefore, when the dog rocker is actuated from a printing` key itis unnecessary to move the separate train of connections to the space key, and vice versa, `thus relieving the resistance to the touch on the keys to this extent. i

A ribbon vibrator 100 is mounted for sliding movement in an inclined plane on a bracket arm of a type guide fixed to the casting 4. The vibrator is detachably connected at- 102 to a link 103 pivoted at 104 to the upper free end of a sheet metal arm 105. This arm forms part of an actuating device 106 pivoted at' 107 to a sheet metal bracket. 108 secured to the carriage support 36. This device 106, 'and the manner of controlling it and regulating the extent of throw of the vibrator', is the same,'or substantially the same, as disclosed in my hereinbefore mentioned Patent 1,397,166. Thus, the slots in the parallel arms of the device 106 receive a bent connecting wire 109 controlled for In either the longitudinal setting movement by a mem- I vforming an operative connection between the universal bar frame and the ribbon actuating device 106. It follows therefore that a case shifting movement of the carriage is effective to produce a corresponding shifting movement of the vibrator 100, the arm 105, the actuating device 106, the rod 109, the arm 110 and universal bar frame, foreand-aft of the machine with the carriage.

A n actuation of the universal bar by any printing key is efective to operate the vibrator, but an actuation of the space key is ineffective on the vibrator.

rlhe vibrator and the parts connected therewith are returned from their actuated position by a contractile spring 111 connected at one end to the arm 105 and at the other end to the cross bar 7 9 of the universal bar frame.

lt will berunderstood from the foregoing that the escapement devices and means for controlling the latter and the ribbon vibrator, are situated near `the bottom vof the machine below the system of key levers, Where they are readily accessible from the bottom of the I machine; that the mechanism is light in construction; maybe easily embodied in the comparatively small space available in the small compact machine in Which it is employed, and the mechanism in use has proved hi hly edcient and durable.
